热Casimir-Polder力测量对轴子参数的约束
Constraints on the parameters of axion from measurements of thermal Casimir-Polder force
摘要：
通过测量$^{87}$ Rb原子的玻色-爱因斯坦凝聚体与SiO $_2$板之间的热Casimir-Polder力，得到了轴子和类轴子与质子和中子的赝标耦合常数的更强约束.为此，计算了由于两个轴子交换作用在凝结云和平板之间的附加力。所得到的约束是指从0.1meV到0.3eV的轴子质量与目前认为最有前途的0.01meV到10 meV的区域重叠。
英文摘要：
Stronger constraints on the pseudoscalar coupling constants of an axion and axion-like particles with a proton and a neutron are obtained from measurements of the thermal Casimir-Polder force between a Bose-Einstein condensate of $^{87}$Rb atoms and a SiO$_2$ plate. For this purpose the additional force acting between a condensate cloud and a plate due to two-axion exchange is calculated. The obtained constraints refer to the axion masses from 0.1meV to 0.3eV which overlap with the region from 0.01meV to 10meV considered at the moment as the most prospective.
